DEVICE FOR THE CLEANING OF SPINNING AP2ABATUS FOR THE MANUFACTURE OF ARTIFICIAL FILAKEN'I'S.

Application filed April 20, 1925. has m. 24,020.

To all whom it may concern:

Be it known that I, HUBERT KEMPF, a

citizen of Germany, and a resident of Barmen, Germany, have invented a certain new 5 and useful Improved Device for the Cleaning of Spinning Apparatus for the Mannfacture of Artificial Filaments, of which the following is a specification.

In the case of apparatus for spinningartificial silk, such as that descrlbed in my prior-application No. 705,138, which comprises a glass cylinder with a glass funnel located therein, the cleaning liquid is introduced at the bottom of the cylinder. This has the result that it first mixes with the precipitant which is in the space between the funnel and the cylinder and on this account it first reaches the funnel itself in a condition which is too dilute. Consequently it requires a comparatively long time before the cleaning is finished, and, on the other hand, after the termination of the cleaning, it is again rather a long time before the cleaning liquid has completely disappeared 2 out of the space between the cylinder and the funnel and pure precipitant is again flowing through the apparatus.

Now it has been discovered that this can be obviated if the cylinder is pierced at the level of the upper end of the glass funnel and the cleaning liquid introduced through a lateral pipe into the aperture at thetop of the funnel. A- hole may equally well be made in the funnel a few centimetres low the upper edge and the supply pipe introduced through this hole.

The invention is illustrated in the accompanylng drawings wherein Figures 1 and 2 show two constructional forms in diagrammatic sectional elevation..

In Figure 1 0. denotes the cylinder, 6 the funnel and a the inlet pipe in the aperture of the cylinder which engages at the top over the edge of the funnel so as to allow of the cleaning liquid ouring into the funnel.

In Figure 2 is illustrated the other com structional form, wherein the funnel also is pierced and the tube for the cleaning liquid is introduced into the funnel t rough this aperture.

What I claim is 1. Apparatus for the manufacture of artificial filaments, comprising aspinnin funnel, an outer casing enclosingsaid f unnel,

said outer casing having a hole in its side in,

the neighbourhood of the level of the top of the funnel, and a pipe for the supply of cleaning liquid passmg from the exterior of 1 the apparatus through said hole to the interior of said funnel.

2. Apparatus for the manufacture of artificial filaments as claimed in claim 1, said funnel being formed with a hole in its side i a short distance below its mouth and said pipe passing through said hole.

In testimony whereof I have signed my name to this specification;

, HUBEBT KEMPF.
